When you need an abrasive media to assist in the dry ice blasting process, the medium used is important to achieve proper surface preparation, whether removing rust or preparing for an applied coating, such as paint or sealant. General Abrasives Co. Inc provides crushed garnet media blasting as an alternative to silica sand that produces less dust and is safer for both wet and dry abrasive blasting.


Regular dry abrasive blasting creates a massive dust plume, leaves blast grit on the cleaned surface and surrounding areas, and friction and heat on the product surface can possibly lead to warping. An industrial approved alternative to traditional sandblasting, blasting with dry ice that has been supplemented with crushed garnet media increases the ability to remove paint and other coatings in sensitive environments by significantly reducing waste and dust generated during the removal process. 

  • Wet or Dry Blasting 

  • Variety of Media Sizes 
  • Non-Toxic 

  • Recyclable up to 5x 

  • Increases Productivity 

  • Less waste and dust generated by traditional abrasive media 

  • Does not leave residual media on the surface of the product

  • Cleans without water, eliminating the need for drying time

  • Environmentally responsible and worker-friendly cleaning method

An environmentally friendly option, crushed garnet can be reused several times in the blasting process, with the medium becoming more rounded with each use. A low-dust and silica free alternative to sandblasting, garnet is ideal for use in wet environments, saving time thanks to it’s deep and precise cutting versus other media options. This is especially useful when preparing concrete, aluminium or fiberglass substrates. All three must typically be prepared to accept thick outer coatings and in many situations, a surface profile must be achieved to allow the coating to properly “grab” the substrate. With crushed garnet, you can achieve a surface profile from 1-4 mils. 


Dry ice blasting uses a pressurized stream of dry ice pellets instead of using small, abrasive particles for blasting. The dry ice is initially solid and begins to sublimate (instantaneously turn to gas) upon impact. The addition of crushed garnet adds an abrasive component and assists in the removal as surface coatings like paint oil, adhesives, and accumulated debris shrink from the change in temperatures and are forcibly blown off the surfaces they are attached to, leaving a clean, dry substrate. By using dry ice with abrasive media, you can avoid the need for containment, waste cleanup, drying time, and any post-cleaning prep before moving on to recoating.

Safe for delicate substances, including wood, stone, and masonry, crushed garnet has been successfully implemented into historic preservation and restoration work, thanks to the minimal amount of dust created. With the ability to implement simple containment measures, this medium allows cleaning in place without impeding on the surrounding environment.

Used within a wide range of applications, the use of dry ice blasting greatly reduces the chance for damage during the cleaning process, while also decreasing the down time of machines being taken out of service for routine cleanings or surface preparation. One of the biggest advantages to dry ice blasting is the elimination of toxic chemicals within the cleaning process, reducing both the damage to the environment and to the overall health of your employees, customers, and contractors.

Eliminating the need for chemical stripping or sanding, resulting in a smooth finish with minimal residue, crushed garnet is superior to softer, less dense media, providing a consistent surface profile while scouring deep into cavities and pitted surfaces to remove all rust, salts and contaminants. By reducing the dust created during this process, there is less disruption to adjoining work areas and a safer working environment with improved visibility. Garnet abrasives can scour deep into cavities and pitted areas to reveal the bare metal, removing surface contaminants that can prevent good bonds with new coatings.

Creating extensive time and cost savings, this removal method requires less media than traditional sandblasting, and also eliminates the need for pre-and post washing, containment, setup and waste collection. Coupled with the fact that this method leaves the surface completely dry and free of residue, you are able to save valuable time on your jobsite. Creating a uniform surface profile, and suitable for use on aluminum and fiberglass, enclosed tanks, dry docks and more, crushed garnet is available in a variety of media sizes.


General Abrasives Co. Inc. provides a variety of dry ice cleaning services; a valuable alternative to sandblasting or abrasive cleaning methods for many products. This service is similar in concept to both power washing and dry abrasive blasting but only in that both methods clean a surface and/or remove paint and surface contaminants.
